netdev-linux: Make queue 0 the default QOS policy

This patch defines, by convention, queue 0 as the default queue in
a particular QOS.  Thus, if queue 0 is defined, all traffic going
through the relevant interface will be enqueued in it. If queue 0
is not defined then ovs will send the traffic directly through the
interface without applying any policy to it.
